Federer produced one of his most complete performances of the tournament to dispatch the 10th seed in just under two hours.

The 17-time major winner was at his clinical best and Tsonga, whose best result at a grand slam came when he reached the final of the Australian Open in 2008, did not have an answer.

Federer appeared to have a plan to get to the net and it well and truly paid off.

Of the 41 rallies in which he approached, the four-time Australian Open champion won 34 points.

One of the most brutal for the usually jovial Frenchman came while he was down 2-4 and 0-30 in the third set.

After Federer comfortably reached a drop shot, Tsonga was too casual with his volley and Federer replied with a backhand winner to set up three break points.

Tsonga was clearly infuriated as he let out a scream after the point, but responded brilliantly to save all three break points and hold serve.

But in the next game he netted a return on what was his only break point of the match and, despite holding serve to make it 5-4, he could not stop Federer from serving out the match. Fittingly, Federer's match-winning shot was a volley.

"I'm playing great," she said when asked about her quarter-final match-up.

"I think I have nothing to lose and hopefully I can play even better than I did today."

Radwanska has only beaten Azarenka three times from 16 meetings between the pair

And while the men's quarter-finalists are almost all at the top of the rankings, the women's side of the draw is a different story.

Of the top eight seeds, only three (Azarenka, Li, Radwanska) have made it through to the quarter-finals.

Sixth and seventh seeds Petra Kvitova and Sara Errani were rolled in the opening round by Luksika Kumkhum and Julia Goerges respectively - neither of whom are ranked inside the top 70.

Top seed Serena Williams played through a back injury in her fourth-round loss to former world number one Ana Ivanovic, while another Serb, eighth-seeded Jelena Jankovic fell to the in-form Simona Halep.
